I had the same problem with Strava a while back. Google Maps worked fine but the GPS in Strava had me jumping from one side of the river to the other. I just rebooted my iphone and it sorted the glitch out for the next ride.

My brother was having issues with no gps signal on his iphone when using strava (to his VERY great anger, guess who copped the brunt of it ) so he got his wife to get him a Garmin 200 for his birthday, problem solved.

When man invented the bicycle he reached the peak of his attainments- Elizabeth West.

Finally joined Strava last week. I busted my iPhone mount on the commuter so switched to the garmin on commutes and stopped using cyclemeter. It's already totally changed the way I ride . So I've joined the ACF club as I don't have enough Strava mates to challenge. Hope to see you out there!

The phone and strava app are just to handy not to use. You take the phone with you where ever you go and it uploads straight from the phone when done. I use a cateye micro wireless on the bike just to see how in going as I ride and throw the phone into my jersey pocket.

Does software or website exist that displays what gear you are in on a map? By that I mean something like instead of a single colour line indicating the route you took, there would be a line that changed colour to indicate the gear you were in. It would be a nice training tool to see how and when you select gears for hills, sprinting and cooling off. Especially useful on a map indicating the topography.

You can look at your or others cadence, but it would be interesting to show the gear selection to obtain that cadence

This should be possible, with cadence and speed measurements, but I guess you would have to enter your gear ratios. Would be great if it could be clearly displayed.
